although it is not limited in its capacity to winding strips for the articles mentioned.

"One object of this invention is to enable strips of paper or analogous material to be wound upon a mandrel and to permit the mandrel to be withdrawn without injury to or disturbance of the articles so formed.

Another object of the invention is to cause the mandrel when presented to the paperrec'eiving guide to always be adjusted in position to receive the end of the strip of paper to be wound and in such' manner that the mandrel may grasp the same.

Another object of the invention isto cause a tension to be applied to the strip that is being wound during the entire time of its winding, and, furthermore, to provide such an arrangement that more or less pressure may be brought to bear upon the article being wound or rolled, so that the same shall be wound with the desired degree of tightness. Another object of the invention is to so arrange the parts of the machine that they may be adjusted so as to enable articles of varyingilength to be produced without a material alteration of the device. I

The invention consists in a winding or rolling machine comprising longitudinallymovaole mand rel, means for causing the same to rotate upon its being placed in its normal operative position, and means for guiding strips of paper or analogous material to such mandrel to enable such strips to be wound.

The invention also iOOllSlSiS in a winding or rolling machine comprising a longitudinally-movable mandrel, means for rotating the same, and means for causing the mandrel to return to a normal paper-receiving position after it has stopped rotating. This portion of the invention comprises a longitudinally-movable rod or bar carrying the mandre1,-a rotative wheel, a clutch having one portion carried by said wheel and the other portion connected with the rod that carries the mandrel, and a jaw or cam adapted to cause the second-mentioned portion of said clutch to come to a normal position after beingdisengaged from the complemental part of the clutch ready to permit the mandrelto be moved forward again to the paper-receiving position. v v

The invention further consistsin a winding and rolling machine comprising a mandrel adapted to wind strips of paper upon it, a guide adapted to present the strips of paper to the mandrel, and means for causing the guide to bear upon the strip being rolled upon the mandrel with more or less pressure, so as to cause the convolntions of the strip to be drawn more or less closely together.

The invention also consists in a winding or rolling machine comprisinga bed, a mandrel, means for rotating the same, means for moving the mandrel longitudinally in either direction, a support for the mandrel and the parts that operate it, said support being adj nstably connected with said bed, and a paper-receiving guide to present strips of paper to the mandrel.

'The invention further consists in the novel details of improvement and the combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein-- Figure 1 is a plan view of a winding or rollingmachine embodying our invention, show:

Upon the bed 1 is mounted a stool? or support 3, which is shown composed of a base 3 and uprights 3 3. (See Fig. 4.) The stock 3 is shown provided with a bolt 4, having a nut 5 topass through an opening 1 in the bed 1, and 6 is an apertured "drel 9, upon which the strips of paper or other analogous material are to be wound; The

threads 10, that mesh with corresponding threads in a socket 10 in rod 8. At the inner end of tube 7 are screw-threads 11, that mesh with corresponding external threads on a plug 12, that is-provided with a bore to receive the mandrel 9, and said plug is shown provided with holes 12 to receive a spanner or other tool for adjusting the same. This plug 12 serves as a guide for the mandrel 9 as the latter is reciprocated. The mandrel 9 is adapted to have forward and back movement for placing it in position to receive the strip to be wound and for disconnecting it from the article when wound, and it is also adapted to have rotary motion for winding such strip. The means we have shown for reciprocating the mandrel 9 consists of lever 13, that is pivotally connected with. rod' 8 and also pivotally connected with a link 14, that is pivoted at 15 toa support 16, that extendsfrom the stock 3 or its upright 3".

By

ver 13 can be shifted to move rod 8 and mandrel9 longitudinally back and forth. It is evident, however, that other means may be provided for reciprocating said rod and mandrel.

The means we have shown for rotating the rod 8 and mandrel-9 consist of a pul- .ley 20, adapted to be driven by a belt '21 or otherwise, and a clutch that is adapted to permit rod 8 and mandrel 9 to be rotated intermittently. We have shown the pulley 20 as mounted upon a sleeve or tube 21, that surrounds the tube 7 and is located at one part in upright3, being suitably held therein, and projectsinwardly therefl om between the uprights 3? 3; The sleeve or, tube 21 at its outer end is shown provided with a flange or right 3, and 23 is a collar fitting on tube 7 and serving to press flange 22 against upright 3, and 24 is a screw threaded in an aperture in collar'23 arid impinging against tube 7 to'hold said collar firmly in place thereon. The hub of pulley 20 is shown provided with an annular groove 20, that receives a finger 25, that projects from a plate 26, secured upon upright 3. pulley 20 is enabled to rotate freely, but is prevented from having longitudinal movement on sleeve 21. It is evident, however, that pulley 20 and sleeve 21 may be otherwise guided and held, if desired.

The clutch for rotating rod 8 and mandrel 9 through the medium of pulley 20 is as follows: 27 is 'a pin projecting from pulley 20, and 28 is a projection or wing projecting from a bar 29, which bar is located in a longitudinal groove 30 in therod 8. Thewing 28 also passes through a groove in tube 7, and the arrangement is such that when pin 27 en'- The lever 13 is shown comprised in By this means means of the above-described device the leextension 22, adapted to abut against the uptoo gages wing 28 it will cause said wing to rotate tube 7 and rod 8, and thereby rotate the mandrel 9 and plug 12. '8 shall have a certain arnountof longitudinal movement independent ofwing 28, and for this purpose-We have shownthegroove 30 as extending near to the inner end of mandrel 9, at which point the groove stops, thus It is designed that rod forming an abutment 30, which abutment serves to engage bar 29 or .wing 28 to move the latter out of engagement with pin, 27.

Within groove 30 is also located a stop orpin- 31, that is adapted to engage the end of bar 29 to push wing 28 into engagement with pin '27 at the proper time. This stop 31 can be"- adj-usted lengthwise of v rod 8 when it is fd'esired to cause wing 28 to engage pin 27, sooner or later, during the longitudinal movement of rod 8.

The mandrel 9 at its outer end is shown tapered, as at 9", and adapted to fit within a corresponding socket 32 in a tailpiece 33, carried by a stock 34, secured upon bed 1. \Ve have shown the stock 34 as projecting from a plate 35, that is supported upon bedl and shown provided with bolts 36, that pass through said bed and through washers or plates 37 and have nuts 3R,whereby said plate 535 may be adjusted upon said bed and securely held in position. In order to grasp a strip 40 of paper or other suitable material to be wound or rolled, the mandrel 9 is shown bifurcated or slotted toward its outer part, as at 9, and the strip 40 is adapted to be passed into said slot and between the arms of the mandrel, as shown clearly in Figs. 5 and (5, so that when the mandrel is rotated it will cause the strip 40 to be wound in parallel convolutions, as indicated in Fig. (3. It is desired that the slot 9, when the mandrel is presented in position to receiv'e the strip 40, shall be automatically brought to the proper position for receiving suclrstrip. For this purpose we have shown a pair of cam-like jaws 41, which extend above and below and in alinementwith the slots in rod 8 and tube 7, respectively. These jaws above and below incline from their outer ends rearwardly to a central point and are located in such position that the wing 28 will engage them when drawn backwardly, if such wing is not in the proper position to cause the slot 9 in mandrel 9 to be brought into position to receive the strip 40. Suppose that when the mandrel 9 comes to rest by the disengagement of clutch 27 28 the wing 28 is out of the normal position for presenting the slot 9 to strip 40. A continued rearward movement of said wing, produced by the engagement of abutment 30 therewith, will cause said wing to engage one of the cam-faces 41, and as the wing rides against such face the wipg will be moved to its normal position at the inner end of said cam-face, and during such movement of wing 28 the rod 3 and tube 7 will be brought to their normal positions, thus causing mandrel 9 to present its slot 9 in position to receive strip 40, as indicated in dotted lines in Fig. 1, where the wing 28 is shown as having been drawn into the recess produced by two cam-faces 41.

42 is a spring-finger that passes across the cam-jaws 41 near theirinner ends and in such position as to lie upon orin front of the wing 28, so as to retard the advance of such wing, which might occur throughthe frictional engagement of the parts, until the stop 31 abuts against the end of bar 29, in which event such bar and wing 28 will be pushed forward against the tension of spring 42, and the wing will thus pass therefrom. It will be seen that there are a p2 of cam-jaws 41 on opposite sides of tube 7 and a spring 42 for each' of such pair of cams, whereby the wing will be brought to a normal central position,- either above or below, to always present the slot 9 to mandrel 9 in position to receive strip 40. The cainjaws 41 extend from a sleeve 43, that is located in the bore of upright 3" and surrounds tube 7, and said sleeve may be held upon said upright by means of a screw or otherwise. The sleeve 43 is shown provided with a flange 44, that abuts against upright 3", and upon the tube 7 is a collar 45, secured thereto by a screw 46, the

collars 23 and thus serving to keep tube 7 in proper position in uprights 3 3, while permitting such tube to rotate.

The means we have shown for guiding the strips 40 to the mandrel 9 are as follows: 47 is a table orguide-plate having one end alincd with mandrel 9, upon which table' the strips 40 are to be laid and fed to said mandrel. (See Fig. 5.) By preference the table 47 has walls 48 on opposite sides, and by preference these walls are connected by cross-bars 49, that overlie the table 47 at suitable distances to allow the strips 40 to pass thereunder. The inner end of table 47 liesadjacent to the mandrel 9 and preferably in the normal position on the same plane as the slot 9 in said mandrel, so that the strip 40 can pass directly into said slot. (See Fig. 5.) By preference the inner end of said table is provided with a plate 50. In order to permit free roll: ing of the strip 40, the inner end of table 47 is provided with a roller 51, that is adapted to abut against the mandrel '9 and also against the roll or tube 40 as the strip 40 is being wound; (See Fig. 6.) The roller 51 is shown journaled upon a shaft 52, thatis carried by extensions from the walls 48 or otherwise. In order to permit of the gradual increase in diameter of the roll or tube 40 as it is being wound by mandrel 9, the table 47' is arranged to tilt, and for this purpose we have shown the table as pivotally supported that are secured or otherwise mounted upon rod 53. The parts 53 54 55 are detachably connected together, so as to permit of the ready interchange of tables 47 of different-widths, collars 53 being shown secured upon rod 53 to keep the table 47 in the proper position laterally relatively to the mandrel 9. The table is preferably held in its normal positionthat is to say, the roller 51 is in engagement with mandrel 9-by a spring 56, which is shown connected'with bracket 54 and with an arm 57, depending from table 47. We have shown the bracket 54 as provided with a number of holes 54 to receive. the hook end of spring 56, and we have shown the opposite end of said spring as connected with a hook 58, that is carried by arm 57. .By this means the tension of spring 56 can be readily adjusted; but it is evident that other means may be provided forthis purpose. We also preferably ICO provide a suitable stop to limit the upward movement of table 47, and for this purpose We have shown a finger 59, carried by table 47 and adapted to abut against a stop 60, carried by plate 35. This stop is preferably vertically adjustable and is shown in the form of a headed bolt screwed into athreaded aperture in plate 35 and provided with a lock-nut 61 to hold it in position. By this means we are enabled to adjust the roller 51 in normal position relatively to mandrel 9, so as to limit the amount of pressure th'ausuch roller can apply to said mandrel.

The complete operation of rolling a strip in convolute or tubular form upon the machine above described is as follows: Lever 13 is first moved to its extreme outward position, as shown in Fig. 2, which causes the wing 28 to bring the slot 9 in mandrel 9 in position to receive the strip 40 from table 47. Lever 13 is then moved in the opposite direction or inwardly, which causes mandrel 9 to advance across in front of roller 51, and after said le- 1 ver has been moved a certain distance the stop 31 will encounter bar 29, thus moving wing 28 forwardly, and just before said wing comes in line with pin 27 on pulley (it being understood that said pulley is continuously rotated) the movement of lever 13 is stopped, and then the end of strip 40 is passed through or into slot 9? in mandrel 9, being so pushed by the operator, it being understood that the outer upper end of said strip 40 is first supplied with a suitable gum. Lever 13 is next moved inwardly until the end 9 of mandrel 9 enters recess 32, during which time wing 28 is brought into line with pin 27 of pulley 20,

whereupon said pin causes said wing to rotate the tube -7, rod 8, and mandrel 9. As mandrel 9 thus rotates it winds the strip 40 upon itself in the form of a coil, as shown at 40* in Fig. 6, and as such coil increasesin diameter the table 47 will be tilted, as shown by dotted lines in Fig. 5, the spring 56 keeping a tension or pressure of roller51 upon the coil. After the strip 40 is completely wound and as its gummed end passes over roller 51 the gum will cause the outer end of the strip to adhere to the next inner layer. Lover 13 is next moved outwardly or to the left in Fig. 2, which withdraws the wing 28 from pin 27, thus causing the mandrel 9 to come'to rest, and during this movement of the lever said mandrel is withdrawn from the roller 40, which falls away, and the wing 28 by engag-. ing one of the cam-faces 41 causes the mandrel to be so turned as to bring the slot 9 again in line with the upper surface of table 47 ready to receive another strip. Thus it will be seen that the operator merely has to move the lever 13 back and forth and feed the strips 40 into the slot of the mandrel 9 in order to eifect the rolling of the articles desired. It will be understood that the length of the article or tube thus formed will be determined by the width of the strip 40 that is supplied, and in this connectionmand-rels 9 of different lengths and tables 47 of difie rent widths will be substituted and the stock or head 3 will be adjusted along, the bed 1 in ac- 'cordance with the length of mandrel to be used.
